I read 3/8 of a book on one day, and 4/5 of the remainder on another day. If now there were 30 pages unread, the book contains:

• Let x be total no. of pages in the book.
  You read 3x/8 pages on 1st day and 5x/8*4/5=x/2 pages on another day.
  Remaining no of pages=30.
  (3x/8)+(x/2)+30=x
  Therefore x=240

• let x is the total no. of pages.
  then remaining unread pages after first day=x-(3x/8)=5x/8
  no. of read pages on second day=(5x/8)*4/5=x/2
  hence total no. of read pages after second day=(3x/8)+(x/2)=7x/8
  unread pages=x-(7x/8)=x/8
  and x/8=30
  so x=240
  hence Answer is 240 pages.
  Thank You...

• 3x/8: 1st day so reamaning page 1-3x/8= 5x/8
  
  for 2 day first day also be consider 5x/8*4/5=x/2 pages on second day
  
  Unread pages=30.
  
  (3x/8)+(x/2)+30=x
  
  So final result will be x=240

• let x be the total number of pages
  On one day he reads 3x/8 of the book
  another day he reads 4/5 of remaining =x(5/8)(4/5)
  now left over is 30 pgs
  therefore,
  x=(3x/8)+(20x/40)+30
  on solving,
  x=240

• 3/8th work completed it means remainig is 5/8th so
  (5/8*x)(4/5)=x/2 it means remaing work is only half is completed
  so x/2=30
  x=60
  total pages are 8*60=480

• let x be number of pages in the book
  then, 3x/8 + 4x/5(5/8) + 30 =x
  on solving we get 240

• 3x/8+5x/8*4/5+30=x
  =>x=240

• let the total no of pages is x;
  x*3/8+(x-3/8*x)*4/5+30=x
  u solved it
  then find the values of x=240
  x/3=30
  x=240 ans

• ANS: totally 240 pages.one day i read 90 pages and another day i read 120 pages remaining 30 pages unread.

• (30*5)=5x/8
  x=240

• let x is the total no. of pages.
  then remaining unread pages after first day=x-(3x/8)=5x/8
  no. of read pages on second day=(5x/8)*4/5=x/2
  hence total no. of read pages after second day=(3x/8)+(x/2)=7x/8
  unread pages=x-(7x/8)=x/8
  and x/8=30
  so x=240
  hence Answer is 240 pages.
